CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2022/001700, filed on Feb. 3, 2022, which is based on and claims the benefit of a Korean patent application number 10-2021-0019448, filed on Feb. 10, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The disclosure relates to a method and electronic device for displaying shared information based on augmented reality (AR).

BACKGROUND ART

Augmented reality (AR) may be technology that combines a virtual object or information with an existing environment so that the object or information is shown as if it originally existed in the environment. An electronic device for providing augmented reality may obtain, using a camera, a preview image of an object in reality, and may recognize (identify) the object in the reality. Based on the recognized object, the electronic device may display information (e.g., a virtual object) associated with augmented reality on the preview image. The augmented reality may be provided to a user via, for example, a game application or a camera application, and may be shared with another user.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

FIG. 1 is a diagram illustrating an operation of obtaining a plurality of images by an electronic device as the electronic device moves, according to an embodiment of the disclosure.

Referring to FIG. 1 , the electronic device 100 according to an embodiment may display an image on a display based on execution of an augmented reality (AR) application. For example, the image may include a preview image that is obtained via a camera.

According to an embodiment, the electronic device 100 may obtain a plurality of images via a camera as the electronic device 100 moves in the state in which an AR application is executed. For example, the electronic device 100 may obtain a first image 101, a second image 103, a third image 105, and a fourth image 107 as the electronic device 100 moves. According to an embodiment, an image obtained as the electronic device 100 moves may at least partially overlap an image that has been obtained immediately before the corresponding image is obtained. For example, the second image 103 may at least partially overlap the first image 101, the third image 105 may at least partially overlap the second image 103, and the fourth image 107 may at least partially overlap the third image 105. According to an embodiment, images obtained as the electronic device 100 moves may not overlap each other. For example, at least two images among the first image 101, the second image 103, the third image 105, and the fourth image 107 may not overlap each other, and may include an area corresponding to the movement trajectory of the electronic device 100.

According to an embodiment, while an image is output, the electronic device 100 may produce a virtual object that is displayed in a manner of being superimposed on the image according to a user input. According to an embodiment, the electronic device 100 may display, based on a user input, a virtual object on the display in the form of an image or text.

According to an embodiment, the electronic device 100 may obtain posture information and/or position information of the electronic device 100 that correspond to each of a plurality of images obtained via a camera. According to an embodiment, the electronic device 100 may detect a posture of the electronic device 100 or a change of the posture via a sensor. According to an embodiment, using a gyro sensor (or a gyroscope), a gravity sensor, a geomagnetic sensor, or an acceleration sensor, or a combination of at least two thereof, the electronic device 100 may sense the rotation of the electronic device 100, a change of the orientation of the electronic device 100, or the degree of slope of the electronic device 100. According to an embodiment, using a position detection sensor and position coordinates 130, the electronic device 100 may sense the location of the electronic device 100.

According to an embodiment, the electronic device 100 may obtain pieces of identification information respectively corresponding to a plurality of images obtained via a camera. For example, the electronic device 100 may obtain first identification information 111 corresponding to the first image 101, second identification information 113 corresponding to the second image 103, third identification information 115 corresponding to the third image 105, and fourth identification information 117 corresponding to the fourth image 107.

According to an embodiment, the plurality of pieces of identification information may include sensing information of the electronic device 100 and scene information including information associated with a virtual object, which respectively correspond to images. The plurality of pieces of identification information may include sub-identification information. In addition, a plurality of pieces of sub-identification information may be information associated with a single piece of main identification information.

For example, the main identification information may include sensing information of the electronic device 100 and scene information including information associated with a virtual object, which corresponds to an image that obtained for the first time. As another example, main identification information may include sensing information of the electronic device 100 and scene information including information associated with a virtual object, which correspond to an image including a largest number of feature points or having the highest definition.

In addition, as an example of sub-identification information, the sub identification information may include sensing information of the electronic device 100 and scene information including information associated with a virtual object, which correspond to an image which is different from an image that is obtained for the first time. As another example, the sub identification information may include sensing information of the electronic device 100 and scene information including information associated with a virtual object, which correspond to an image different from an image including a largest number of feature points or having the highest definition.

According to an embodiment, the electronic device 100 may store the pieces of sub-identification information 111, 113, 115, and 117 by merging the same with a single piece of main identification information 120. According to the above-described example, the electronic device 100 may process the sub-identification information by merging the same with the single piece of main identification information 120, and thus, may efficiently use and manage data.

According to an embodiment, based on the second image and the second sensing information (e.g., the position information and/or posture information of the electronic device 100), the processor 210 may obtain second identification information corresponding to the virtual object in operation 480. According to an embodiment, if a change in the movement (e.g., rotation, translation) of the electronic device 100 falls within a designated range and if a range of overlap between the first image and the second image is less than a threshold value, the processor 210 may obtain the second identification information based on the second image and the second sensing information. For example, if the change of the movement of the electronic device 100 is greater than or equal to a first threshold value and less than a second threshold value, the processor 210 may determine that the range of overlap between the first image and the second image falls within a designated range. In addition, for example, if the number of feature points extracted from the second image that are identical to feature points extracted from the first image is less than or equal to a designated number, the processor 210 may determine that the range of overlap between the first image and the second image is less than a threshold value.
